Net Income Per Share

14. NET INCOME PER SHARE

The following table sets forth the computation of basic and diluted net income per share for the periods indicated (in thousands, except per share data):

	Three Months Ended February 28,
	2012		2011
Net income attributable to TIBCO Software Inc.	$	20,641	$	15,953
Weighted-average shares of common stock used to compute basic net income per share		161,460		160,503
Effect of dilutive common stock equivalents:
Stock options to purchase common stock		7,307		10,255
Restricted common stock awards		2,099		2,728
Weighted-average shares of common stock used to compute diluted net income per share		170,866		173,486
Net income per share attributable to TIBCO Software Inc.:
Basic	$	0.13	$	0.10
Diluted	$	0.12	$	0.09

The following potential common stock equivalents are not included in the diluted net income per share calculation above because their effect was anti-dilutive for the periods indicated (in thousands):

Stock options		1,912		381
Stock awards		23		—
Total anti-diluted common stock equivalents		1,935		381

In fiscal year 2010, we granted 4.1 million performance-based restricted stock units ("PRSUs") that contain performance metrics based on the attainment and maintenance of specified non-GAAP EPS goals. If the performance criteria are achieved, these PRSUs will be considered outstanding for the purpose of computing diluted EPS if the effect is dilutive. The dilutive impact of these awards will be deferred until the performance criteria has been met, which at the earliest is as of the first quarter of fiscal year 2013.
